In today's interconnected world, English proficiency has become a critical skill for engineering students, as it significantly influences their academic success, career prospects, and ability to collaborate internationally. As the global language of science, technology, and engineering, English serves as the primary medium for technical communication, research dissemination, and participation in multinational projects. This paper explores the necessity of learning English for engineering students, examining how proficiency in the language impacts their performance in academic settings, their future employment opportunities, and their involvement in global engineering innovations. Through a mixed-methods approach, combining surveys, interviews, and literature analysis, the study investigates the challenges faced by non-native English-speaking students, the role of English in technical writing and presentations, and strategies for improving English skills within engineering curricula. The findings suggest that English proficiency is indispensable for accessing the latest research, communicating effectively in international teams, and advancing in the global job market. Furthermore, the paper highlights the importance of integrating English language training into engineering programs to equip students with the necessary skills for both academic excellence and professional success. The study concludes with recommendations for educators and institutions to enhance English language support within engineering education, ensuring that students are fully prepared for the demands of the modern engineering landscape.
